The purpose of this study is to clarify motives, itinerary and general patterns associated with the traveling of the upper class in the Chosun Dynasty based on twenty travel accounts of Mt. Chungryang. In addition, previous studies were referred to in order to compare these trips to Mt. Chungryang with those which were undertaken to Mt. Kumgang so as to identify the unique characteristics of those involved with the trips to Mt. Chungryang and of these trips in themselves. Through this process, unique characteristics, such as the travelers' academic backgrounds and place of origin, as well as how these travelers' relationship with their teachers influenced the motivation for these trips were uncovered, as were the processes through which travel schedules and companions were selected. Moreover, the researcher identified similarities and differences between the travel of Mt. Chungryang and Mt. Kumgang in terms of the travelers' motivation for the trip, the transportation methods they employed, and the kind of accommodation they sought. Moreover while similarities were also uncovered with regards to the travel practices of the literati class during this time, differences emerged in terms of their travel dates and schedules.

Telehealth is widely tested in the U.S.A and other developed countries. This system is expected to solve rural health problems reducing professional isolation. Some demonstration projects showed that the system can provide quality care in reasonable prices to rural residents. However, few study has been done on whether telehealth system can attract physicians by reducing professional isolation. The system is not available to most of the rural hospitals because the price for the equipment and telephone charges are not low enough. It is promising that the system cost and telephone charges are decreasing gradually. As time passes, rural hospitals will be more viable for the system. Satisfaction of the physicians and patients is a key factor for the implementation of the system. The physicians need to understand more about telecommunication and computer systems. After physicians are well-versed about the system, we can expect wide use of telehealth in rural areas. Effort for the confidentiality and standardization should be devoted to assure patient's privacy and compatibility of patient records and exam results. In Korea, two projects are being operated in Uljin and Kurye. A study evaluated the economic efficiency of the projects suggesting that increase of the number of patients up to three times of current number or decrease in hardware costs and telecommunication charges into two thirds of the current costs. The hardware and telecommunication charges are decreasing. Another area telehealth system can be applied is psychiatric accommodation facilities. Establishment of telehealth in the psychiatric facilities will increase the access of psychiatric care for patients and is expected to be economically efficient.

As the number of internet users grows rapidly, the services which users required becomes various. However, for fulfilling these various user requirements, the existing passive network should be standardized for a long time. To resolve the delay on providing services, active network as a new technology was suggested. Its router or switch with DARPA as center has the program running ability, so user oriented network can be composed. However, active network's architecture can resolve the user required service using mobile code on the network node, but it is more complex, easy-to-attack, various than the passive network. Many researchers have tried to resolve this problem. So, this paper studied the mobile code security service in active network environment to provide user's convenience and accommodation, and introduced ANASP system as an alternative.

Objective: The purpose of this study was to investigate differences of shock attenuation strategies between double-leg and single-leg landing on sagittal plane using statistical parametric mapping. Method: Nine healthy female professional soccer players (age: 24.0±2.5 yrs, height: 164.9±3.3 cm, weight: 55.7±6.6 kg, career: 11.2±1.4 yrs) were participated in this study. The subjects performed 10 times of double-leg and single-leg landing from the box of 30 cm height onto force plates respectively. The ground reaction force, angle, moment, angular velocity, and power of the ankle, knee, and hip joint on sagittal plane was calculated from initial contact to maximum knee flexion during landing phase. Statistical parametric mapping was used to compare the biomechanical variables of double-leg and single-leg landing of the dominant leg throughout the landing phase. Each mean difference of variables was analyzed using a paired t-test and alpha level was set to 0.05. Results: For the biomechanical variables, significantly increased vertical ground reaction force, plantarflexion moment of the ankle joint, negative ankle joint power and extension moment of the hip joint were found in single-leg landing compared to double-leg landing (p<.05). In addition, the flexion angle and angular velocity of the knee and hip joint in double-leg landing were observed significantly greater than single-leg landing, respectively (p<.05). Conclusion: These findings suggested that negative joint power and plantarflexion moment of the ankle joint can contribute to shock absorption during single-leg landing and may be the factors for preventing the musculoskeletal injuries of the lower extremity by an external force.

The selection of a flagship industry is based on whether the industry's developmental impact is great and whether the industry can be the center of the national economy. Here, a ripple effect may be derived by analyzing the forward and backward linkage effects, but in the case of industries that are the centerpieces of the national economy, each researcher reported different results. Consequently, they could not agree on their flagship industry despite belonging to the same time. This study presents a prestige centrality of network analysis as a way of analyzing an industry, which was the center of the national economy, and performed empirical analysis utilizing the 2013 I-O Table. The analysis showed that the industries classified as those with high centrality include the energy industry, which is essential for economic development, can create a synergy effect with other industries, such as the transportation industry, industries with a high level of export and employment, such as electronics and chemicals, and industries for domestic demand, such as wholesale and retail, food services and accommodation.

This study aimed to investigate the images that affect general travel behavior and satisfaction of eco-tourists of Section seven of Jeju Olle-gil and to give eco-tourists preferred images to newly constructed eco-tour sections. Adjectives were selected to evaluate images, and for analysis, a survey was carried out with 132 persons who have toured 7 section of Jeju Olle-gil. On this survey, basic travel type, overall satisfaction, image before and after experience, age, gender, satisfaction level and accompanying type were inquired. 81(61.4%) knew section 7 of Jeju Olle-gil 'in advance', and 58(39.1%), which takes up the largest portion in this question, came to choose section 7 by a word of mouth. 95(71.9%) answered that they stayed 2 nights and 3 days, and 55(41.7%) answered that they stayed at a pension as accommodation. As for accompanying type, 34(25.7%) answered they accompanied family and relatives. As for the decision of visit, 60(45.5%) replied that they decided one month prior to the visit. And as for the purpose of visit, 63 (33.8%) replied they visited to appreciate nature. The adjectives that demonstrate overall satisfaction and significance level of the tourists were 'placid', 'refreshing', 'living', 'mountainous' and 'green'. As for the satisfaction level, people were satisfied with its environment, cleanliness level and direction boards. The types of section preferred by the tourists were clay pavements, followed by sand-masa soil mixture pavement and wooden deck pavement. 'Oidolgae' section was selected as the representative section, and 10:00a.m.~12:00p.m. was preferred as visiting time. And it is also proved that people were positive in appointing photo zones.

Of late, demand for test sites for marine equipment such as ASV, AUV, ROV, and various underwater sensors is increasing. The authors have focused on an oscillating water column (OWC), which is being constructed near Chagwido Island Jeju, as one of the test-sites. The main objective of the OWC is to produce wave energy and develop technologies. It has been built in the sea approximately 1 km off the coast. It has berth accommodation and some rooms that can be used as laboratories. To investigate the feasibility of its usage as a test site for marine equipment, we acquired bathymetric data around the OWC by using a multi-beam echo sounder and a single-beam scanning sonar. The accessibility of the OWC from nearby ports and the use of support vessels or ships were also investigated. 3D point cloud data from the multi-beam echo sounder and 2D acoustic images from the scanning sonar are expected to be used as references for identifying changes over time. In addition, through these experiments, we derived a procedure to use this facility as a test site by using the IDEF0 functional modelling method. Based on this preliminary investigation and previously reported examples, we determined the general conditions and preferences for evaluating the performance of various marine equipment heuristically. Finally, we developed five applications that were derived from this investigation.

The COVID-19 outbreak in 2020 caused continuous damage worldwode, especially the smart tourism industry was hit directly by the blockade of sky roads and restriction of going out. At a time when overseas travel and domestic travel have decreased significantly, the number of tourist hotels that are colsed and closed due to the continued deficit is increasing. Therefore, in this study, licensing data from the Ministry of Public Administraion and Security were collected and visualized to understand the operation status of the tourism and lodging industry. The machine learning classification algorithm was applied to implement the business status prediction model of the tourist hotel, the performance of the prediction model was optimized using the ensemble algorithm, and the performance of the model was evaluated through 5-Fold cross-validation. It was predicted that the survival rate of tourist hotels would decrease somewhat, but the actual survival rate was analyzed to be no different from before COVID-19. Through the prediction of the business status of the hotel industry in this paper, it can be used as a basis for grasping the operability and development trends of the entire tourism and lodging industry.

In order to analyze the impacts of climate change, a time and space integrated model was developed in this study using system dynamics and GIS. The model built was used to carry out a simulation on the inundation impact on A-gu of Busan Metropolitan city resulting from the sea level rise scenario of IPCC and storm surge, which is the worst case. Through this, the flooded area and population until 2100 were predicted. Also, the result and significance of each alternative was reviewed improving the model by establishing alternative scenarios of protection, accommodation and retreat as plans of reaction to sea level rise. The combination of system dynamics and GIS has advantages of how the diverse variables change until the target year can be traced and, accordingly, not only the results but also the processes of spatial change can be examined by calculating the value of change process at each time step. The synergy of this model presumed to be a foothold for solving problems which are becoming difficult to predict due to increase in uncertainty and complexity such as the support for decision making for urban resilience to natural disasters.
